Optimizing Gas Desorption and Mass Transfer Kinetics of OER Electrodes via Patterned Engineering
Efficient and stable water electrolysis electrodes are of great significance for sustainable energy conversion. However, conventional catalysts still suffer from bottlenecks such as insufficient utilization of active sites and mass transfer limitations caused by bubble blockage. In this work, a synergistic optimization...

Hierarchical Interfacial Engineering of Gas Diffusion Electrodes for Acidic CO2 Electroreduction in Membrane Electrode Assemblies.
Acidic CO2 electroreduction in membrane electrode assemblies suppresses parasitic carbonate formation and improves carbon utilization. Yet, practical implementations remain hindered by proton accumulation and alkali cation buildup that give rise to failure modes associated with hydrogen evolution, salt precipitation, a...

Enhancing electrocatalytic ammonia oxidation via surface concentration-gradient platinum alloying
Electrocatalytic ammonia oxidation reaction (EAOR) remains hindered by the lack of catalysts that simultaneously achieve high activity and long-term stability. Herein, we report a surface compositional gradient PtFe alloy catalyst (G-PtFe) consisting of a Pt-Fe gradient shell and a PtFe alloy core. The G-PtFe deliv...

Composition-Dependent Microcube NiCoO2 Binder-Free Electrode with Enhanced Diffusion for Efficient Electrochemical Nitrate Reduction to Ammonia.
Electrochemical nitrate reduction reaction (NO3RR) has recently emerged as an environmentally benign route for sustainable NH3 synthesis under mild conditions. However, the complex 8-electron transfer pathway and various intermediates often lead to sluggish kinetics and limited selectivity. Therefore, the mass transpor...

Synergistic Defect-Interface Coupling in CoFe/NiFe/CoFe Layered Double Hydroxides for Efficient Oxygen Evolution Reaction.
The oxygen-evolution reaction for hydrogen generation is a slow reaction process, thus requiring electrocatalysts of high efficiency and earth abundance. Here, we report CoFe-NiFe-CoFe (CNC), a layered double hydroxide heterostructure fabricated on nickel foam by layer-by-layer electrodeposition. This approach allows f...
